摘　　要：针对人的隐性知识在设计决策过程中难以外显,导致决策结果不确定的问题,提出了一种融合视觉感知数据的灰色设计决策方法。基于视觉感知、注意与偏好的映射关系,建立视觉感知认知模型。综合决策者显性维度的主观选择和隐性维度的眼动追踪数据,构建偏好设计决策的评判机制,利用余弦距离来分配决策者权重,利用灰色决策综合排序求得方案的优劣顺序。以电饭煲为对象进行实例研究,结果表明该方法能得到客观、准确的决策结论,可有效应用于信息有限条件下的群体决策,为设计创新提供方法参考。Aiming at the problems that tacit knowledge was difficult to be revealed in the design decision processes,which led to the uncertain decision results,a grey design decision method blending visual perception data was proposed.Based on the mapping among visual perception,attention and preference,a cognitive model of visual perception was created.Integrating the decision makers'subjective choice of explicit dimension and the eye tracking data of implicit dimension,a preference design decision-making evaluation mechanism was constructed,cosine distance was used to assign the weight of decision makers,and the gray decision comprehensive ranking was used to obtain the order of proposals.A case study was carried out on the rice cooker,the results show that the method may obtain objective and accurate decision-making conclusion.This protocol may be effectively applied to group decision-making under the conditions of limited information,and provide method reference for design innovation.
